The World’s Largest Things card # WB20 you found on eBay is mine. I’d really like to know the rarity of it since it’s the only one found on eBay. The first 5, WB1 – WB5, seem to be the most common. The rest, WB6 – WB25, seem to be more rare as only a few are popping up. My friend just pulled the “Book” card which you don’t have on your list and isn’t on eBay either!
